Description
Technical field
The invention belongs to element connection device technical field, more particularly to it is a kind of can two-way fast assembling-disassembling pin shaft structure.
Background technology
At present, the band large-scale metal structural member connection of engineering machinery is main using bearing pin connection or bolt connection.Such as stake work machine
In tool product, the jib lubbing mechanism of rotary drilling rig and vehicle frame, mast, the component such as the carriage arbor of two-wheel flute milling machine and milling wheel transmission case connect
Connect and all connected using bearing pin.These bearing pins connection pin shaft structure feature be：Baffle plate is welded with one end of bearing pin, bearing pin is installed
During to position, baffle plate plays axially position effect, to prevent bearing pin from rotating or play, is locked using round nut in the bearing pin other end
Extremely, or on baffle plate bolt hole is designed, bearing pin is fixed on connected structural member by bolt.
Be can be seen that from existing pin shaft structure feature, one end of bearing pin is welded with baffle plate, and the size of the baffle plate compares bearing pin
Diameter, the pin-and-hole diameter of connected structural member want big.Therefore, after bearing pin loads direction, the negative side in direction can only be loaded from bearing pin
To being removed.And many Constructional Machinery compact dimensions, all it is often that outside has the sufficient space to carry out bearing pin loading, but
Space is removed in inside, when especially working in the wild, lacks instrument accessory, and the larger bearing pin difficulty of dismounting size, weight is huge.
As shown in figure 1, the bottom of two-wheel flute milling machine is some sleepers 13, the carriage arbor 14 of two-wheel flute milling machine and the milling of milling wheel assembly 16
Bearing pin 15 on wheel transmission case is connected.During the dismounting of scene, carriage arbor 14 and milling wheel transmission case are all in order at horizontality, and milling cutter
Frame 14 is big with milling wheel transmission case size, nearly 30 tons of weight, and scene does not possess roll over condition back and forth.It is welded with the bearing pin 15 of baffle plate such as
After fruit loads from upside, can only be from downside（And Fig. 1 plants the direction of arrow）Removed, and lower side space is small, in addition the weight of pin 15
Greatly, whether remove and be also loaded into, can all there is a problem of that difficulty is big and efficiency is low.
Therefore, the pin shaft structure of existing bearing pin connection can not meet the demand of fast assembling-disassembling.
The content of the invention
For above-mentioned prior art exist problem, the present invention provide it is a kind of can two-way fast assembling-disassembling pin shaft structure, from
